To ally whom ttfmay concern Be it known that I, JOHN H. DAMM, of thecity of Milwaukee, in the county ot' Milwaulu e and State of Wisconsin,have invented certain new and useful Improvements in PortableWindow'Railing; and I do hereby declare that the following is a full,clear, and exact description thereof', which will enable others skilledin the art to which it pertains to malte and use the same, referenceheilig had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this speciiication.

This invention relates to improvements in outside railings for windows,iliade portable and adjustable to windows of different widths, and bymeans of which, when adjusted in a window, a person is enabled to standon the outside of the window with safety when washwingrmrepairing it,and consists in the construction and arrangements hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of a windowwith my invention attached thereto. Fig. 2 is a view `of the devicedetached.

Referring to the parts by letters, A A are metallic spring-plates orwindow-railings. B and C are bars of Wood which overlap each other aboutone-third of their lengths, more or less, according to the width of thewindow. D and E are iron clasps. The clasp D is atv tached permanentlyto the bar B, and is loosely clasped around the bar C in such a mannerthat the bar U can be moved to the right or left, as required, throughit when being adjusted to windows oi' different Widths. The clasp E isin like manner attached permanently to the bar C, and clasps loosely thebar B. F is a screw. Gr is a nut or burr, which is firmly attached tothe clasp D. The head of the screw F operates in a swivel, II, which isattached to the clasp K. I is a short arm or projection on the screw F,by which it is turned. L L at the end ot' the bar B, and L L at the endof the bar U, are short iron pins attached to the end of the bars B andU.

The railing is attached to a window-easing for use in the followingmanner: The bars B and C are placed between the window-casings M M, whenthe screw F is turned until the pins L L L L are forced into the casingsM M. By a reverse movement of the screw F the pins are withdrawn fromthe casin gs, and the railing can then be removed.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination of the metallic railing or bars A A with the slidingbars B and C, substantially as and for the purpose specitied.

2. The combination of the metallic railing or bars A A, sliding bars Band C, clasps D, E, and K, and screwrod I", substantially as and for thepurpose specitied.
